EXCAVATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 734,315, dated Ju1y'21, 1903. Application filed June 6, 1201- serial No. 63,442. (Nomodel.)

To all whom it may concern:

Be it known that I, THOMAS H. GARLAND, a citizen of the United States,and a resident of Cleveland, county of Ouyahoga, State of Ohio, haveinvented certain new and useful Improvements in EXcavating-Maohines,ofwhich I hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in excavating-machines; and theobjects of the machine are to provide means-for elevating materialsexcavated and loadingthemupon wagons with greater facility than could bedone by labor.

The machine is especially adapted to excavating deep cavities, such asare made for foundations, from which it would be difficult to drawloaded wagons; and it consists in the combination and arrangement of thedevices hereinafter described, shown in the accompanying drawings, andspecifically pointed out in the claim.

In the accompanying drawings, Figure l is a transverse section of thedevice. Fig. 2 is a plan thereof. Fig. 3 is a side elevation. Fig. 4 isa transverse section on line of shaft of the outer end of thedepressible carrier. Fig. 5 is a diagrammatic View of driving-chains andsprockets.

In the views, 1 represents a wagon-frame mounted upon the usual axlesand wheels 2 and 3 for the sake of portability. Transversely across thismachine is seen an endlessbelt-carrier 4, raised at the outer end ashigh as shown in Fig. 1, so that a wagon can be driven underneath. Thiscarrier is mounted upon drums 6 at the lower end and a'drum 7 at theouter end. The outer end is supported the elevated carrieris theinclosed endless carrier 17, mounted upon drums 12 and 15. The inner endX of this carrier is soplaced as to discharge upon the'carrier 4 andalso pivoted upon its inner shaft 18, so that the outer extremity can belowered nearly fiat upon the To permit the horses to readily cross theplatform, the carrier should be sunk to its level in the earth or thedirt should be heaped about it sufficiently to form an incline on eitherside. With two holes at a slight distance apart two scrapers could bedumped at once if room is left for the horses to pass.

'The carrier 4 is actuated by means of sprocket-wheels 21 and 22,respectively, on the shafts 23 and 24 and sprocket-wheel 25 upon theshaft 27,-connected with engine 28, mounted upon the Wagon platform 16..Chains SO and 31 drive the carrier sprocketwheels, and a chain 33connects sprocket- .wheels 34 upon the drum-shafts 18 and 41 of the morehorizontal carrier. Chain 32 connects the inner shaft 18 and sprocket 40of this carrier with sprocket-wheel 26 upon, the enginadrivenshaft 27.

It will readily be seen that by means of this device the dirt can berapidly scraped upon the platform 19 and transferred at once to theinclined carrier and thence to wagons, thus utilizing machinery in placeof a great deal of manual labor in filling wagons and economizing a vastamount of time.

The carrier 17 and cover 19 are raised and lowered by means of the ropes43 and pulley 42.

In Fig. 4 is shown a detail of the outer drum and sprocket. Here thedrum and sprocketchain are shown connected together by bolts, as 40, sothat their movements must be simultaneous, and any unexpected frictioncan be more easily overcome.

carrier, openings in said platform and means for driving said endlesscarriers and for raising and lowering the same, substantially asdescribed.

In testimony whereof I have signedmy name to this specification in thepresence of two subscribing witnesses.
